※ 304 is a symbol representing a type of stainless steel, and it has the same properties as surgical stainless steel. Material: Stainless steel Size: 40mm long Color: Gold Wire diameter: 0.7mm Ball part: 2mm Quantity: 30 pieces (+ spares) Because the wire diameter is 0.7mm, it is firm and stiff. The ball part is 2mm, which is large, so it is difficult to come off. [Note] Basically, for weighing purposes, we include 1-2 extra pieces. There may also be some bent pieces. (If you are concerned about this during your work, please use nylon pliers to smooth them out.) Please understand this beforehand. Because these are made overseas, there may be stains, misalignments, some defects, deformations, and size errors. Please consider this before purchasing (*μ_μ)♪
